Answer:
21.......
Step-by-step explanation:
7/100. ×300
Answer:
1.2x-1.2y
Step-by-step explanation:
if your wanting to know how far the diver will be down you do 240+25 which is 265
265-80=185 (cause the diver swims up)
185+12+30 =227
227-16 =211
the deep see diver is at 211 meters below the surface
Remark
You need to do some trig to get the final answer. There is no way around it. You can however, solve the first part with the Pythagorean Theorem.
Step One
Find AB
AB^2 = DB^2 + AD^2
AB^2 = 7.5^2 + 4.9^2
AB^2 = 56.25 + 24.01
AB^2 = 80.26
AB = sqrt(80.26)
AB = 8.9588
Step Two
Move to the triangle on your right. Find x
Tan(C)= opposite / adjacent
Tan(55.8) = AB/adjacent
Tan(55.8) = 8.9588/ x Multiply both sides by x
x * tan(55.8) = 8.9588 Divide by tan(55.8)
x = 8.9588/tan(55.8)
x = 6.09
Answer: A
The answer is b.) 120 degrees
